What the area code does and does not tell you
A number that starts with 364 was first assigned in Kentucky. That is a fact about where the number began, and it is a useful hint when you check a form entry, for example a billing address in Kentucky next to a 364 phone number.
It does not show where the person is today. A number stays with its owner after a move or a change of provider (number portability), and mobile numbers travel with the handset. The area code also cannot tell you whether the line is active, who the carrier is, or whether the number is mobile or fixed: the plan shares those ranges.
